RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 451,804, dated May 5,1891.

Application filed January 17, 1891. Serial No. 378,104- (No model.)

To all whom, it may concern.-

Be it known that. 1, THOMAS BROWN, a citizen of the United States ofAmerica, residing at Thurlow, in the county of Delaware and State ofPennsylvania, have invented certain new and useful Improvements inRailroad- Ties; and I do herebydeclare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

This invention relates to improvements in metallic railway-ties.

The objectof the invention is to provide a tie made up substantially ofa single casting having raised and hollow end portions, which arewedge-shaped in cross section and adapted to receive a wooden block,upon which the rail rests and is spiked, said block being retained inplace by end plates, which are bolted to the metallic tie, as will behereinafter fully set forth and particularly claimed.

In the accompanying drawings, forming part of this specification, Figure1 is a side view of a metallic tie constructed in accordance with myinvention, one end of the same being broken away. Fig. 2 is a section onthe line no as of Fig. 1. Fig. 3 is aplan view. Fig. 4 is a section of amodification.

A refers to a casting, which comprises a base-plate a, raised endportions B,anda central web 0. The raised end portions presentreceptacles wedge-shaped in cross-section for thereception ofwedge-shaped blocks E, said blocksbeing preferably made of wood. Theseblocks are held in place by end plates D, which have perforatedprojections which register with lugs 12, formed at the ends of theraised portions B, bolts being employed for securing the parts, asshown. The. rails T rest upon the wooden blocks E and are spiked theretoin the usual manner, and when said blocks are. worn out they can beremoved and new ones inserted without destroying the tie or removing itfrom the road-bed. The plates D may be cut away at their lower edges orbe shortened to not rest upon the base-plate a, so that moisture whichmay collect in the receptacles can pass out.

Instead of having the receptacles wedgeshaped, the side walls may bemade parallel and the upper ends thereof extended inward.

I am aware that prior to my inventionit has been proposed to construct arailway-tie of metal and provide the same with boxes to receive woodenblocks, to which the rails are secured, and I do not, therefore, claimsuch construction, broadly, as my invention; but

What I do claim as new, and desire to secure by Letters Patent, is

In a metallic railway-tie, a casting presenting a base a, wedge-shapedboxes B, having open outer ends and tops, perforated lugs 19, formedthereon, and vertical connectingflange 0, together with retaining-platesD, connected to the casting by bolts to close the outer ends of theboxes and retain therein blocks E, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS BROWN.
